1.
What is ON-Q*?
ON-Q* is a brand name of a continuous infusion pump that delivers medication
(such as local anesthetic) to or around surgical wound sites and/or in close
proximity to nerves for preoperative and postoperative regional anesthesia and/or
pain management.
2.
Is the ON-Q* continuous infusion pump also indicated for epidural use?
The ON-Q* pump may also be used for epidural applications. Refer to the Directions
For Use for specific information on epidural use.
3.
Will ON-Q* continuous infusion pump provide better pain relief than narcotics alone?
By adding the ON-Q* pump to a patient's post-surgical pain treatment, patients will get better pain
relief than with narcotics alone. When the ON-Q* pump is used with narcotics, it reduces the amount
of narcotics needed to relieve pain following surgery. Key studies from various surgical specialties were
submitted as clinical evidence validating these indications. Some clinical studies have also demonstrated
reduced length of stay, which may result in decreased costs, increased patient satisfaction; and a quicker
return to normal function.
4.
How does the pump work?
The pump consists of a multi-layer membrane with a protective PVC cover. The strain of the elastomeric
membrane provides positive pressure of approximately 10 PSI (500 mmHg). A flow controller regulates the
flow rate. The pump is portable and may be placed in a carrying case or clipped to the patient's clothing.
5.
What ON-Q* pump models are available?
Currently there are four pump models:
• ON-Q*: flow restricting orifice controls the flow rate. Flow rate is fixed and cannot be changed.
Also available in dual and triple site configurations.
• ON-Q* with ONDEMAND*: delivers a continuous infusion (basal) and also incorporates a bolus device
that allows fixed boluses to be delivered on demand.
• ON-Q* with Select-A-Flow*: incorporates a controller that allows the user to adjust the flow rate within
a pre-determined range designated on the device. Also available in dual site configuration.
• ON-Q* with Select-A-Flow * and ONDEMAND*: includes an adjustable rate controller and a bolus device.
6.
What is the material in the elastomeric membranes?
The pump consists of three layers:
• The inner layer is a synthetic thermoplastic elastomer which contains the drug and does not
contain natural rubber latex.
• The middle layer is composed of natural rubber latex.
• The outer protective layer is PVC.
The natural rubber layer does not come into human contact.
